Relations with other models

The GLOBIO3 model calculates the global biodiversity, indicated by the surface area of natural ecosystems and the mean species abundance (MSA). MSA is an indicator of the remaining naturalness of terrestrial ecosystems. The MSA indicator is calculated by using dose-response relationships between environmental pressure factors and the abundance of naturally occurring species, relative to their abundance in the (natural) reference situation. Currently, the effects of the following pressure factors are included in the model: (change in) land use, infrastructure and fragmentation, nitrogen deposition and climate change. Results from the IMAGE model (Land-Cover Model, Atmosphere-Ocean System) are used to quantify these pressures (except for infrastructure and fragmentation). The current version of the model includes only terrestrial ecosystems. An extension for aquatic, freshwater ecosystems is being developed.
